Electronic Intake and Exhaust valves (no mechanical valves, cams or timing) are the enabling technology for:
1. Air Compression, storage and re-use in a modified Internal Combustion Engine (Air Hybrid).
2. Variable Compression in a modified Internal Combustion Engine.
3. In conjunction with Electronic Pressure Sensors (to detect ignition) and Direct Injection enable Variable Fuels (any gas or liquid that burns) to be used in a modified Internal Combustion Engine.
